“Standard” is a bit strong, maybe? I think the majority of new homes still use trickle ventilation because it’s much cheaper, and not many homes have them retrofitted?
They are certainly common, but I think far from standard.
- bluGill 4y agoLast I checked 20 years ago it was required. This was Minnesota though, where insulation code is generally more up to date than other parts of the US.
- _benedict 4y agoThe original comment referenced the U.K., where it is definitely not required, but is becoming more common. I am surprised at the idea that MVHRs have been required anywhere for as much as 20 years.
- bluGill 4y agoWhere you are makes a big difference. 20 years ago I read about some 'passive house', and realized it was actually less insulated than the codes in Minnesota require - but it was in a mild climate so it was passive, while the more efficient houses in MN are not passive.
